MINERS LAMP.

SPECIFICATION forming part of Letters Patent No. 326,858, dated September 22, 1885. Application filed April 9, 1885. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN FERN, a citizen of the United States of America, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Miners Lamps, of which the following is a specification, reference being had therein to the accompanying drawings.

My improvement in miners lamps is designed to remedy certain objectionable features which minerslamps ordinarily comprise, and which result from the necessity of raising the lamp-wick at intervals. In raising the wicks pin known asa lamppicker, but in the absence of such a pin they usually strike the lamp upon a stone or upon the soles of their shoes; but always upon any hard or solid ob- These methods of raising the wick are exceedingly objectionable. The pin for raising the wick is often missing when needed, and when at hand, in using it, a large part of the wick is unevenly raised and wasted, and striking the lamp, as aforesaid, results not only in jarring the top of the lamp open and wasting the oil, but in the destruction of the lamp-spout by the rough usage to which thus subjected. It follows that the ordinary miners lamp, which should last for years, is thus soon rendered leaky or knocked to pieces.

My improvement consists in the peculiar construction, combination, and arrangement of the parts of my miners lamp to overcome these objectionable features, as hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of a miners lamp embodying my improvement. Fig. 2 is a modification of my invention. Fig. 3 is a sectional view of the same on the line a" 00. Fig. 4 is also asectional view on the line y y of Fig. 1,- and Fig. 5 is a side elevation, the ferrule being omitted.

In the construction of my miners lamp, to avoid the recited objectionable features, 1 providea transverse slot-opening, B, near to the end of the lamp-spont, of size sufticient to therein admit apronged orforked instrumenta wick-raiser, in fact, hereinafter more fully referred toand then clamp or otherwise rigidly attach to the lamp-spout the ferrule B, having formed therein an aperture, 0, which is caused to register with slot B. The sheet metal of which ferrule B is formed is curved or bent slightly over in aperture 0 at B in order to form a slight projection for the looped or turned-up end a of the slide D to abut against. End a of slide D also retains the slide on the ferrule. The slide D is disposed between the inside of ferrule B and the spout A, and is arranged to slide forward as a means of uncovering slot B and aperture 0, which I are ordinarily tightly closed to prevent escape of their lamps miners usually employ a sharp I of oil, and also to prevent coming ignited at that point; and in order to furnish sliding space for slide D between the inside of the ferrule and the lamp-spout, ferrule B is thereat correspondingly enlarged to cover it. Ferrule B is rigidly secured to the end of spout A by forming aperipheral ridge on the lamp-spout, on which is enclasped the annular concave recess b of the ferrule.

The wick-raiser I is a flat metallic bar having an eye, 9, for attaching itit may be by means of chain gto hinge bracket 9, and tangs or sharp points h, which in practice are inserted through the slot 0 in the ferrule B and aperture B and into the wick, which may be thus raised out of the spout uniformly.

A modification of myinvention is shownin Figs. 2 and 3. It consists in ferrule E, attached as an annex-spout to spout F of lamp G, the method of attaching it to the spout being similar to the method described of attaching ferrule 13 to its lamp, and it is provided with an aperture for insertion of a similar wick-raiser, which aperture is provided with a turned-over lip, 6, against which the corresponding lip, f, of slide H abuts. Slide H is adjnstably secured on the end of ferruleE by bending over the outer fold of the metallic strip of which it is composed and inserting its outer end beneath lip f.

Myimprovement is also equally well adapted for torches and lanterns, and may be manufactored and applied to the lamp at little cost.

Having thus fully described myinvention,
